FAST II works in combination with the motorcycle’s ECU and is designed to provide fuel and ignition adjustment capabilities in a single unit. FAST II will work with any exhaust, but maps have been developed that specifically work with LeoVince SBK Exhausts. The basic kit includes the FAST II control box, which comes pre-loaded with three exhaust-specific maps; a model-specific wiring harness; all the necessary hardware for installation; and a CD with directions and FAST II software.
